To atZZ whom it mag concern:

Be it known that I, GEORGE a citizen of the United States, Washington,in the District of Columbia, haveinvented certain new and usefulImprovements in Elevated Electric Tramways, of which the following is aspecification.

This; invention has relation to elevated electric tramways especiallyadapted to be used for transportation purposes; and it consists in thenovel construction and arrangement of its parts, as hereinafter shownand described. I

The object of the invention is to provi e a ramway of the nature asindicated to be used for transporting mail and express or freight matterfrom point to point. To accomplish this, a rigid or inflexible track issupported upon vertical su ports. The said track is composed of railswhich are substantially cruciform in cross-section, and hence byresiding at their formation are braced against the strains usually metwith in such constructions. The supports for the track areisosceles-shaped in side elevation and are mounted at their bases uponsuitable ties or foundations embedded in the ground. Supplementaltrackwa s are mounted upon the supports at points below the track-railand are adapted to sustain the greater port-ion of the weight of thecars or carriers, while-the track rail is used mainly for tractionpurposes and as a ground return for the electric current. Suitable bondsare provided at the ends of the track-rails. Current-wires are-suspendedabove the trackway and are ada ted to transmit the elec- .tr1c currentto t e cars or carriers. Also suitable arch supports of specialconstruction are provided forsupporting the current-wires. The cars orcarriers are of s ecial construction and are es eciallyadapted vtrackways suc asindicated. Theframeo 'the car or carrier is providedwith depending hangers, which extend down on opposite sides of thetrackwa and are curved up at their lower ends. The said hangers arerovided with rollers which run upon the supp emental trackways, and thusretain the caror carrier in erect position upon the trackway irrespec-50 tive of the unevenness of the weight of the load carried on eitherside of the said car or G. SoHRoEDER,

tobeusedu on carrier. Thus it is not necessary to exercise great care tohave the car or carrier properly counterbalanced upon the trackway.Cylindrical receptacles are provided to be carried by the'upcurved endsof the said hangers; Said cylinders are divided by partitions into upperand lower end compartments. Each door, so that the contents of onecompartment-may begotten at without disturbing the contents of any othercompartment.

are adapted to be used for the transportation of mail, while thecompartments at the opposite end of the cylinder are adapted to be usedfor transporting express matter. The upper heavier bulky packages, whilethe lower comages containing fragile articles.

In the accompanying drawings, Figure 1 is a side elevation of a portionof the tramway, showing a carricrthereon in side elevation also. Fig. 2is a transverse section of the tramway-track, showing the support inelevation and the current-wires support in elevation. Fig. 3 is aperspective view of a modified form of carrier-frame. Fig. 4 is adetailed enlarged side elevation of the meeting ends of the track-rails.Fig. 5 is a transverse sectional view, enlarged, of the trackrail. Fig.6 is a detailed enlarged side elevation of the meeting ends oft'hesupplemental rails with parts broken away. Fig. 7 is a detail enlargedside elevation of a fish-plate used upon the trackway. Fig. Sis alongitu- ,dinal sectional view of one of the carrier-cylinders, and Fig.9 is an end elevation of one of the carrier-cylinders with the upperportion in section.

The track-rails l aremade cruciform in cross-section and are providedwith the top traction-surface 2 and the vertically-disposed sidesurfaces 3 3. The cross ledges or webs 4 4 are located substantiallymidway between the upper and lower edges of the rail. At their ends'theelectric bonds 5 are provided, which are secured at-their ends to theends of the opposite or meeting Tails 1 1. The fishcated over the bonds5 The channels 7-recompartment is provided with a separate Thecompartments at one end of the cylinder compartments are intendedtocontain the partments are intended to receive the packplates 6 v6 arechanneled, as at 7, and are 10- ceive the said bonds, and the saidplates are bollted to the lower portions of the meeting ra1 s..

The track-rails are supported by the up.- rights- 8, which aresubstantially isosceles in shape in side elevation and which rest attheir bases upon the ties 9 or other foundations suitably embedded inthe ground. The sockets 10 are formed at the upper ends of the supports8. The lower edges of the rails 1 rest in said sockets with theinsulation 11 interposed between the walls of the sockets and the saidrail edges. The bolts 12 pass transversely throu h the upper ends of thesaid supports 8 an( the lower portions of the rails 1. K

The chairs 13 are attached to the sides of the uprights 8 and supportthe supplemental track 14. Said supplemental track is preferably made ofpipe-sections screw-threaded together at their ends. The bolts 15 arecountersunk at their heads in the supplemental track 14 and pass throughthe chairs-13 and form an attaching means for the said supplementaltrack. The arches 16 are supported at the upper ends of the posts 17 17and are connected at their ends to the upper ends of the said posts bymeans of the unions 18 18. The said arches extend over the track 1..

The telegraph or telephone wire-supporting pins 19 19 are mounted uponthe arches 16. The hangers 20 depend from the centers of the arches 16and are provided at their lower ends with the cross-arms 21, whichsupport at their ends the current-wire 22 22. The said wires 22 extendparallel to the track 1. a

The motor 23 and its attachments are of especial construction to travelupon the track herein described. The said motor is provided with theusual trolley-arm 24, the wheels of which run against the under sides ofthe current wires 22. The tractionwheels 25 of the motor are arranged intandem and travel upon the traction-surface 2 of the rails 1. The saidwheels are provided with the side flanges 26 26, which bear against theside surfaces 3 3 of the said track and prevent any tendency on the partof the motor to lateral rock. The hangers 27 27 depend fromthe frame ofthe motor 23 and extend down on each side of the track 1. The lower endsof the said han ers 27 are upwardly hooked, as at 28, am are adapted toredeive and support the cylinders 29. The under sides of the hangers 27are provided with. the rollers 30 30, which travel upon the supplementaltrackways 14 14 and prevent the weight of the load carried by a cylinder29 on either slde of the track 1 from can-ting the vertical axis of themotor 23 with relation to the track 1. The lower ends of the hangers .27are provided with the fretwork 31, and in some instances the saidrollersmay be attached to the said fretwork instead of directly to the lowerends of the hangers.

The cylinders 29 are divided by the horizontal partition 32 into upperand lower compartments and by the transverse part1- tion 33 into endcompartments. The .upper compartments are provided with the doors 34 34,which are hinged to the sides of the cylinders, and the lowercompartments are provided with the doors 35 35, which are hinged to theends of the cylinders. The compartments at one end of the cylinder areada ted to receive and contain mail-matter,

whi e the compartments at the opposite. end of the cylinder are adaptedto receive and contain expressage. The top compartments hold articles ofa durable nature, and the bottom compartments hold fragile articles. Thecontents of one compartment may be reached without disturbing thecontents of any other comp artm ent.

in the formof the invention as shown in Fig. 3 the side bars 36 of theframe of the motor are provided at their ends with the series ofperforations 37 37 and. the upper and lower horizontal rods with theconnections 38 33,

)V and rear hangers may be adjusted with relation. to each other.

From theforegoing description it is obvious that as the motor travelsupon the track 1 the rollers 30 30 will travel upon the supplementaltracks, 14 1 1 and that the weight of the loads carried by the hangers27 will be borne principally by the said supplemental tracks, while thetrack 1' will be used principally for traction purposes. By thisarrangement it is not necessary to exercise care to have the loadproperly counterbalanced upon the track 1.

The wires 22 22 are used for the purpose of transmitting the electriccurrent to the Inctor, while the track 1 is used as a ground-return forthe current. The chairs 13 13 are disposed toward the centers of thecylinders 29 29, and consequently the weight of the said cylinders is ina direct thrust against the said chairs. The parts are so arranged thatthe possibility of any tendence to lateral sway or rock when thecylinders are loaded.

or empty is positively prevented.
